This invention relates to base-closures for vertical gas retorts and gas chambers and especially to that kind of base-closures which allow the removing of distillation products 5 from the lower part of the retort or chamber.

In the existing base-closures'the door is provided with a hood, which is open at one longitudinal side, near to the inner Wall of the chamber or retort.

The characteristic features of this invention are that the hood is divided into two halves nearly in the direction of the middle longitudinal plane of the chamber; that one half is closed and. constructed as a normal protecting hood for the door, while the other half is open both at the inner side towards the middle of the chamber and at one front end, and that in one front wall of the chamber a gas-outlet communicating with the in- 0 side of the open half of the hood is arranged.

The advantage of such a construction of the hood is that the gases escaping at the lower end of the chamber must continually pass through the comparatively cool middle coal-core so that the gases remain cool and do not decompose. If steam is introduced through the open half of the hood it flows over the whole middle plane of the contents of the chamber, whereby a complete decomposition of the steam is achieved, so that a water gas of more uniform and steady composition than by means of the existing closures is obtained. V

In the accompanying drawings, a base closure according to the invention is illustrated by way of example.

Fig. 1 shows a vertical cross section through a gas chamber.

Fig. 2 shows a vertical longitudinal section.

1 Fig. 3 shows a vertical cross section through the lower part of the gas-chamber in an enlarged scale.

Fig. 4 shows a vertical longitudinal section through the lower part of the gas-chamber, also in an enlarged scale.

The gas-chamber a has at the lower end a cover 0. This cover 0 is provided with a hood. According to the invention this hood is divided into two parts in the longitudinal direction of the chamber.'- Part'n is closed 6 i and serves asa normal protecting and insulating hoo'd for the closure-door'o'. -The other" part p is open at'the inner'longitudinal sidea; Thelateral aperture of this open part p is about in the middle longitudinal plane ofthe chamber a. Thepartrp ofthe-hoodfis elevated at the end at sand is also-open. The open end projects into a recess iof the front wall of the chamber. on

In this front wall-of the chamber aa gas-outlet 0 communicating with the interior of the. part 39 of the hood is'arranged. The x object of the elevation s is to enable a proper and unrestrained removal of the distilled gases into the lower eduction pipe 0. Y

The part 39 ofrthe hood may assumeany shape, but betweenthe door 0 and thepart p of the hood there must be afree space q for.

leading off the gases; Though the coal lying T on the parts a and p of the hood can throughthe lateral aperture ofthe-partp enter the interior of this part,-it cannot fill up the en tire inner space of the part 19, .for it lies under its-natural angle. of slopea (Fig.4). an

There is therefore above the coal and at its side a free'passage g for. the distilled gases, which can reach the pipe 0 through the el e+ vated end 8 of the part 10 of the hood."

The-ribs r'in'the open part ofthe hood serveas supports to relieve this part from'tthe pressure of the coal weight and to transfer it to the base-closure 0.1 i

For the introduction of steam a duct opens into the pipeline 0. Forthe'pur'pose'i of forming water gas suchsteam is blown, in the known way, through the pipeline 0" 1 after the gasification' of thecoal, into hot coke. The steam flowsthrough the-free space 1 g of the part per the hood into-the'inside of the chamber a and it meets'and this is of special importance -the hot coke'in the diher, one half is closed and constructed as a normal protecting hood for the door, the other half is open both at the inner side towards the middle of the chamber and at one front end, a gas outlet in one front Wall of the chamber, said gas outlet communicating with the inside of the-open half ofthe'bonnet.
